Zachary D. Rowitsch 16abbd78e7 Bulk-import 2899 WPT CSS reftests and add import tooling
Add scripts/import_wpt_reftests.py to sparse-clone the upstream WPT repo
and bulk-import qualifying CSS reftests (no JS, no external resources) as
known_fail entries. 23 tests already pass and are promoted. The import
script is idempotent and exposed via `just import-wpt`. CI now prints the
WPT summary (pass=36 known_fail=2877 skip=1) on every run.
